Abstract
The paper compares two approaches for developing Web service interfaces for the vertical integration of TTP/A fieldbus systems. High-level abstractions are provided by application specific interfaces, generated from metadata describing fieldbus systems. In contrast standardised interfaces such as OPC XML DA only allow lower levels of abstractions. But these enable accessing the fieldbus system from a broad range of standard clients, while high-level abstractions reflecting the application programmer's view on the system facilitate the development of more specific clients and workflows.
本文比较了两种用于TTP/A现场总线系统垂直集成的Web服务接口的开发方法。高级抽象由特定于应用程序的接口提供，这些接口是从描述现场总线系统的元数据生成的。相比之下，标准化接口(如OPC XML DA)只允许低级别的抽象。但是，这些允许从广泛的标准客户端访问现场总线系统，而反映应用程序程序员对系统的看法的高级抽象促进了更具体的客户端和工作流的开发。
